--------------------------------
Summary: Introduce period compaction to FRocksDB
Key: FLINK-30457
URL: https://issues.apache.org/jira/browse/FLINK-30457
Project: Flink
Issue Type: Improvement
Components: Runtime / State Backends
Reporter: Yun Tang
Assignee: Yun Tang
Fix For: 1.17.0
RocksDB supports period compaction once compaction filter is enabled (see
https://github.com/facebook/rocksdb/wiki/Leveled-Compaction#periodic-compaction),
which is really useful for Flink TTL feature to pick really old files in
compaction.
Current FRocksDB base version: 6.20.3 has included the necessary code on the
C++ side: https://github.com/facebook/rocksdb/pull/5166 and
https://github.com/facebook/rocksdb/pull/5184. We just need to cherry pick the
https://github.com/facebook/rocksdb/pull/8579 on the java side to support it in
Flink.
